Patent EP-0288605-A2 (EP)
Inventor: IKEDA YASUHIRO
IPC: C30B13/30
Filed: 1987-12-14
Abstract: In a method of controlling a floating zone of a semiconductor rod of the present invention shown in Fig. 1, the diameter D s  at a crystallization boundary of a crystal and the axial length of the floating zone are indirectly controlled by controlling a diameter D m  of a crystallizing-side melt shoulder portion and the diameter D n  of a constricted melt portion, respectively. Since these diameters D m  and D n  are used for predicting D s  and L to be obtained after a given time has passed, the response speed and stability of the control are improved as compared with the direct control of D s  and L. An apparatus for controlling a floating zone of a semiconductor rod of the present invention performs the above-described method. In another method, the zone length is directly or indirectly controlled by regulating a relative moving speed of the melting-side semiconductor rod relative to the heater, and the diameter D s  at the crystallization boundary of the crystal is directly or indirectly controlled by regulating the electrical power supplied to the heater.

Abstract: The carriage (12) is displaced by a toothed belt (33) which is driven continuously by an electric motor (48) and is connected to the carriage by means of a drive element (32) engaged between two teeth of the belt and slidable on bars (27) on the carriage in a direction perpendicular to the direction of displacement of the carriage. The pulleys are provided with recesses (42, 43) capable of engaging the drive element in such a way as to move it positively in the perpendicular direction as it moves round a pulley. The carriage is also connected by means of a tension spring (58) to a strip (52) provided with indicia of an optical encoder, sensed by an optical reader (57). The upper paper pressure arrangement is formed by two rollers (85) carried by two sliders (83) fitted into corresponding longitudinal slots in the fixed support. The paper is carried by a feed reel which is carried by two arms (94) which can be fitted by catch engagement on corresponding shoulders on the fixed support. The printer is particularly suitable for being connected to the output of a personal or home computer.

IPC: G02B6/44

Abstract: The long term water instrusion resistance of cable splice systems that use a gelable encapsualtn that is pressurized prior to gelation can be improved by providing pressurization means that maintain the pressure on the cured encapsulant above a given pressure p 2  > p 0 , where po is the ambient pressure. Absent such pressurization means, the pressure on the encapsulant typically decreases with time due to creep or relaxation of nominally rigid components, e.g., a plymeric closure around the encapsulated splice, or vaires due to differential thermal contraction. The pressurization means comprises one or more energy storage elements, e.g., an elastic member such as a spring, or a volume of compressed gas. In a preferred embodiment, an elastomeric "bag" (23) is formed around the completed cable splice, the two havles (24, 24') of a plastic closure placed around the bag, the two halves fastened together with spring clamps (30), liquid encapsulant introduced into the bag, and the encapsulant pressurized to a pressure pi > p 2 . The spring clamps typically are dimensioned such that a gap exists between the two halves of the plastic closure for any pressure ≧ p 2 , at any temperature within a specified temperature range, at least up to the design life of the splice system. The existence of the gap assures that the spring clamps maintain pressure on the encapsulant within the closure.

Abstract: passive propellant management system for a spacecraft liquid propellant tank (1) comprises several preferably V-shaped channels (2) which communicate liquid propellant from regions within the tank (1) to an outlet port (8), which expels liquid propellant but not pressurant gas. A liquid/bubble chamber assembly (9) couples the channels (2) with the outlet port (8). The channels (2) comprise relatively open portions (11) and relatively closed portions (10). In the relatively open portions (11), liquid is retained in a gap (12) between open ends of the V channels (2) and the inner wall of the tank (1 ). In the relatively closed portions (10), a screen, mesh or perforated plate (14) covers the open end of the V channels (2), intermediate the V channels (2) and the inner wall of the tank (1). The placement of the relatively open and closed portions (11, 10), respectevely is intentionnally preselected based upon mission requirements. Where pressurant gas ullage is expected to be present, e.g., during period of high g, relatively open portions (11) are used. Where liquid propellant is expected to be present, e.g., during periods of relatively low g, relatively closed portions (10) are used. The liquid/bubble chamber assembly (9) comprises a liquid trap (27) and bubble trap (28), which operate synergistically with each other and with the channels (2) to provide optimum liquid flow during all phases of the spacecraft mission.

Abstract: The insert, to be set in concrete, for ensuring the desired position of reinforcements in reinforced concrete building components consists of at least two stirrups, which are open towards the formwork and welded together by means of longitudinal bars to form a unit, and at the stirrup ends of which the internally threaded sleeves are arranged, which are equipped with holding elements for the lower reinforcement, while the upper reinforcement is supported by the stirrup crosspieces or the longitudinal bars. The concrete covering for the upper reinforcement is ensured by the fact that the height of the stirrups is adapted to the desired position of the upper reinforcement. The insert is characterised in that it serves both to ensure the desired position of the reinforcements and, after the concrete has set, permanently, if necessary, as a constructional reinforcement for suspended loads acting on the underside of the building component and/or as a shear reinforcement. <IMAGE>

Abstract: A CVD process for the treatment, in particular for the individual coating, of substrates, in particular for semiconductor components, is to be improved with regard to the required processing time and the uniformity of the result obtained. It is proposed initially to accumulate the used gas mixture (5) in a chamber (10) and then to pass it as a gas stream (12) via a nozzle (11) to the substrate (1) and to activate the CVD process with the aid of a laser beam. Several additional measures for further activation of the process and for monitoring and regulation of an automated process are possible as embodiments. The process can be used in semiconductor technology for the metallisation of substrates or for the passivation of pn junctions. Furthermore, structuring of substrate surfaces can be carried out by this process. <IMAGE>

Abstract: The two mutually coaxial supply nozzles (4) for cold and hot water open at right angles to the flow direction (a) of the control disc stack (2) through the wall of the housing (1) into the pressure equalising device (3). The two water flows are deflected through 90 DEG in this device. This leads to a very compact fitting which means a small installed depth in the case of mounting under the plaster and a small projection in front of the installation wall in the case of mounting over the plaster. Both arrangements are of particular advantage, particularly in the case of shower mixing valves in relatively thin-walled confined shower cubicles. <IMAGE>

Abstract: Method and apparatus for determining Young's Modulus of a specimen by measuring the speed at which stress waves, either P-waves or S-waves, propagate therein. An embodiment of the apparatus includes two fixtures (120, 140) which are removably affixed to opposite ends of the specimen. A hammer having an accelerometer (14) affixed to its head is used to strike the first fixture (140) to produce stress waves in the specimen. A timing means (400) starts counting in response to an output generated by the accelerometer when the hammer strikes the first fixture. A second accelerometer (24) affixed to the second fixture (120) detects the stress waves and generates an output which causes the timing means to stop counting. Further circuitry (425) extracts the measured time, calculates a dispersion time delay based on material and length, and subtracts the dispersion time delay and a predetermined constant, both dependent on the material in the specimen, from the measured time to form a corrected transit time. The circuitry uses the corrected transit time to determine the propagation speed of the stress waves and Young's Modulus therefrom.
